| Example: |
The program,
import yoix.*.*;
JFrame frame = {
Array layout = {
new JCanvas {
String text = "hello, world";
Color background = Color.black;
Graphics graphics = {
String font = "Helvetica-bold-12";
Color foreground = Color.yellow;
};
paint(clip) {
double x;
double y;
x = size.width - stringWidth(this, text) - 72./4;
y = size.height - graphics.font.descent - 72./4;
drawString(this, text, x, y);
}
},
};
};
frame.visible = TRUE;
sleep(5);
exit(0);
prints a string near the lower right corner of a canvas.
stringWidth
and font metric information is used to figure out where to place the
string so it all shows up properly.
